FASTENING DEVICE.

Appllcation'flled January 19, 1921.

, To all whom it may concem:

Be it known that I, FREDERICK E. MARKERT, a citizen of the United Statesof America, resi-din at Number 579 East 161st street, borough of theBronx, city and State of New York, have invented certain new andusefulImprovements in Fastening'De vices, of which the following is aspecification.

This invention-relates to improvements in separable fastening devicesand is especially adapted for use as an awning fastener, but is alsocapable of being used as'a fastener for other devices made offlexiblematerial having reinforced edges and likely to be subjected to heavystrain and hard usage such as carriage curtains, door hangings, and thelike.

It is an object of the invention to provide a device of the characterdescribed which will be simple,,and, therefore, economical in itsconstruction, but at the same time thoroughly practical and reliable asa means for accomplishing its intended purpose.

In the drawings illustrating certain forms of the invention,

Figure 1 is a view in cross section, showing the invention applied as anawning fastener, as a means for securing the top of the awning to thehead of a window frame.

Fig. 2 is a view of thesame in front ele vation.

Fig. 3 is a view of the'blank fromwhich the fastener, illustrated inFig.1, is made.

Fig. 4 is a perspective view of the same form of the invention, theprongs having been cut and-bent in readiness to be secured to the edgeof the awning or other device to which thefastener is to be applied.

Fig. 5 is a side View of the fastener of the form illustrated in Fig. 1,the edge of the article to which it is attached being shown in crosssection.

Specification of Letters Patent.

Patented Nov. 1, 1921. Serial No. 438,398.

Fig. 10 is a face view of a fastener of a second modified form,illustrated as applied to supported.

Fig. 11 is a section on the line 11-11 of F 1g. 10.

Referring more particularly to Figs. 1 to 5, the preferred form of theinvention will first be'described as applied to an awning 20 having afold at 21 inclosing a reinforcing element 22.

In Figs. 1 and 2, a fastening device 23, which may be made of steel orany other approprlate material, is provided with a longitudinal slot 24adapted to be passed over a screw-eye 25 secured in a head 26 of awindow frame. a

The fastening device is also provided with prongs 27, 28 and 29 (Fig.4), by which the fastener may be secured to the edge of the awning. Thefastener is also provided with a notch 30 in the upper wall of the slot24., the prong 29 being formed of material cut from the slot 24 andnotch 30, as indicated in broken lines in the blank, Fig. 8.

To secure the fastening device to the awning, the prongs 27, 28 arepassed through the fabric just below the reinforcing strip, and turneddown against the surface with their points directed toward the margin.The prong 29 is at the same time passed over and around the margin ofthe awning and bent down against its surface with its end directed awayfrom the margin. In this manner, the fastening device is very firmly andpositively secured to the edge of the awning, the strain beingdistributed over a considerable portion of the same by means of theinclosed reinforcing element.

To apply the fastening device to the head of the window frame,thescrew-eye 25 is given a quarter turn to a horizontal position. Theslot 24 is then passed over the screw-eye and the screw-eye returned tothe position illustrated in Figs. 1 and 2. The notch'30 drops over theshank of the screw-eye and forms a satisfactory centering means, capableof preventing undesirable endwise movement of the attached awning.

In Figs. 6 to 9, inclusive, is illustrated a modified form of fasteningdevice 23 having prongs 27, 28 corresponding to the the same being thearticle to be prongs 27, 28 of Fig. 4. In this "form, however, in placeof the prongs 29 there is provided a pron 29 out from the lower part ofthe blank Fig. 8), and turned upwardly against the body of the fastener,and forwardly as illustrated in Fig. 9, in readiness to be passed overthe margin of the awning. This form of the device is alsoprovided with aslot 24: and notch 30 corresponding to the slot and notch of the formillustrated in Fig. 4c.

The device in the form illustrated in Fig.

'9, is attached to the edge of an awning 20,

and the prongs turned down against the part inclosing the reinforcingelement 22', as illustrated in Figs. 6 and 7. It is then adapted forattachment to the screw-eye or other appropriate means of support, inexactly the same manner as has been described with reference to the formillustrated in Figs. 1 and 2.

In Figs..1O and 11 is illustrated another .modified form, which differsfrom that illustrated in Figs. 1 to 5, inclusive, only in that thefastening member is provided with a circular opening 31 adapted toreceive a rope or cable as a means of support, instead of the screw-eyeillustrated in Figs. 1 and 2. It

may be observed thatin this form ofthe 7 It will be understood that theinvention is 7 not limited in its application to the particular formsherein disclosed, but is intended to include all such other forms andmodifications as fall within the scope of the appended claims.

What I claim is 1. The combination, with the reinforced edge portion ofan article of the character described constructed of flexible material,of a fastening device of'rigid material having a body portion in contact:with one face of said edge portion, a prong extending from j said bodyportion through said edge portion at a point removed from the margin andbent down against the other face,'with its end extending toward saidmargin, and another prong extending forwardly from said body portion atsaid margin and bent down against the last mentioned faceof said edge;
